Foundation Repair Mosier
Foundation issues can lead to significant damage to your home if not taken care of. If you live in Mosier, OR, you might see signs like cracks in your floors, bowing walls, or sagging floors that indicate deeper structural problems. Homeowners may also notice doors that stick, windows that don’t close properly, or visible gaps between walls and ceilings. These symptoms could mean that your foundation is shifting due to soil movement, water damage, or the effects of aging.
At TerraFirma, we specialize in foundation repair right here in Mosier, offering expert solutions that address the root causes of your foundation issues. Our process starts with a thorough inspection to evaluate the extent and source of the problem. After that, we recommend one or more of our reliable foundation repair systems:
Foundation piers
Our push and helical piers are expertly designed to stabilize and lift your foundation by transferring its weight to deeper, more reliable soil. In Mosier, helical piers work great for known soil conditions, while push piers are an excellent choice for areas with uncertain stability. Both options are minimally invasive and provide lasting solutions for your foundation needs.
Wall Stabilization Systems
For cracked, bowing, or leaning walls, we offer a suite of reinforcement products. These include:
- CarbonArmor®: Made from fiber-reinforced polymers ten times stronger than steel.
- PowerBrace®: Zinc-plated steel beams that can be tightened over time.
- GeoLock® Anchors and Helical Tiebacks: These systems halt inward movement and gradually straighten walls over time.
- EverBrace™: Designed for severely deteriorated walls, this system replaces and reinforces failing foundation walls with steel supports.
We also offer grouted micropile tiebacks for difficult soil conditions, SmartJack® crawl space support posts for sagging floors, and vapor barriers to manage humidity and prevent further moisture damage.
Every solution comes with expert installation, ongoing maintenance options, and transferable warranties, ensuring you have confidence and peace of mind in your home here in Mosier.
Basement Waterproofing Mosier
Having a damp basement in Mosier can result in mold, mildew, structural damage, and poor air quality in your home. Look out for warning signs like musty odors, stained walls, pooling water, or a white, powdery residue known as efflorescence that appears when water evaporates. Even a small crack in your basement wall can let in a significant amount of moisture.
TerraFirma provides top-notch basement waterproofing solutions in Mosier, ensuring your space stays dry, healthy, and functional—come rain or shine.
Crawl Space Repair Mosier
Crawl spaces in Mosier, OR, are often forgotten, yet they play a vital role in your home’s structure and air quality. If left untreated, a neglected crawl space can become a breeding ground for mold, pests, and standing water. These issues can lead to wood rot, unpleasant odors, and even respiratory problems for you and your family.
We understand the unique crawl space conditions in Mosier, OR, and TerraFirma’s crawl space repair services are tailored to tackle moisture, mold, pests, and sagging floors with comprehensive encapsulation, effective drainage solutions, and robust structural support.
Encapsulation & Drainage
We begin by sealing the crawl space with our VaporLoc Elite liner, a 120-mil thick waterproof barrier that blocks moisture, soil gases, and allergens. To ensure proper drainage:
- We use drainage matting under the liner to guide water to your perimeter drain or sump pump.
- Sump pumps remove water quickly and efficiently, even during heavy rain or high water table conditions.
Crawl Space Entry & Vent Solutions
- EverLast™ Doors & Access Wells: Waterproof, durable entry systems that keep out pests and moisture.
- Turtl™ Access Well: An attractive, lockable access solution in several colors.
- Vent Covers: Sealing crawl space vents prevent outdoor air, moisture, and insects from entering.
Crawlspace repair in Mosier is crucial to maintaining your home’s overall health and energy efficiency.
Structural Repairs
To support sagging or weak floor joists, our SmartJack® Support Posts offer adjustable, galvanized steel columns that restore floor stability. These are fast to install and offer permanent results.
Dehumidifiers & Monitoring
Install a SaniDry Sedona dehumidifier to maintain healthy humidity levels year-round. For added security, our ShipShape™ System offers 24/7 performance monitoring, proactive maintenance alerts, and remote control of your crawl space systems.
Concrete Repair Mosier
Damaged, cracked, or uneven concrete isn’t just an eyesore—it’s a safety concern. These issues can arise from poor soil compaction, freeze-thaw cycles, erosion, or even tree root growth. Homeowners in Mosier trust us to promptly and effectively restore their concrete slabs, sidewalks, patios, and driveways.
TerraFirma provides quick, reliable, and durable concrete leveling and repair services in Mosier, OR, using state-of-the-art polyurethane foam injection and expert crack sealing.
PolyLevel® Concrete Lifting
PolyLevel utilizes expanding polyurethane foam to lift and stabilize concrete slabs. This non-invasive method is perfect for residents of Mosier, OR, looking to:
- Sidewalks – Eliminates tripping hazards and restores smooth walkways.
- Driveways – Prevents further cracking and improves curb appeal.
- Patios, Porches, and Pool Decks – Ensures proper drainage and surface stability.
NexusPro™ Crack & Joint Sealant
To prevent water intrusion that can lead to further sinking, we apply NexusPro, a UV-resistant silicone-based joint sealant that:
- Cures in just 60 minutes.
- Withstands extreme weather and heavy use.
- Includes color-matched sand for a clean, polished look.
SealantPro™ Concrete Protection
After sealing and lifting your concrete, SealantPro provides a long-term barrier against moisture, chemicals, and seasonal temperature changes. It penetrates deep into concrete to resist stains, flaking, and surface erosion.
We also provide commercial concrete repair in Mosier, OR for industrial buildings, warehouse floors, roads, runways, and rail lines—using the same high-quality systems we trust for residential properties.
Earthquake Retrofitting Mosier, OR
Much of the Pacific Northwest, including Mosier, is located in an active seismic zone. Homes constructed before the updated building codes introduced in the 1990s are particularly at risk. Even a minor earthquake can lead to homes shifting off their foundations or suffering significant structural damage.
TerraFirma’s earthquake retrofitting services help secure your Mosier home to its foundation and strengthen its ability to withstand seismic events.
Enhancing your home with earthquake retrofitting in Mosier not only helps protect your property, but it can also lower your insurance premiums and deductibles, making you eligible for coverage that may not have been available before.
How We Retrofit
Assessment & Planning
In Mosier, OR, the retrofitting process starts with a thorough assessment of your building’s current state. An expert—like a structural engineer or a trained technician—will inspect your home to pinpoint any weaknesses and suggest the best solutions.
This assessment involves checking the foundation, walls, roof, and overall structure of your building. After that, our engineer will create a detailed retrofitting plan tailored to the results.
Foundation Bolting
Strengthening the foundation is the next step in our process. Our skilled technicians will install anchor bolts to firmly connect your home to its foundation, keeping it stable and secure during an earthquake.
In Mosier, our process includes drilling holes into the foundation and inserting steel bolts. Our team then tightens these bolts to reinforce the structure, improving its stability and resilience against seismic activity.
Adding Shear Walls
Shear walls are essential for earthquake retrofitting in Mosier, OR, as they help distribute seismic forces and keep buildings from collapsing.
Shear walls, often made from plywood or other durable materials, are installed in key areas of your home, especially in cripple walls, to enhance structural support and stability. This helps minimize the risk of damage during an earthquake, ensuring your Mosier home stays safe and secure.
Bracing & Reinforcing
Next, we focus on strengthening key areas of your home in Mosier with durable steel braces and straps. Our team expertly installs these reinforcements on essential structural components like the roof, walls, and floors. This crucial step enhances your home’s overall stability, ensuring it has a solid framework that can withstand seismic forces.
Securing Applicances
Securing your appliances can help make your home in Mosier safer for everyone. It’s important to anchor items like water heaters and refrigerators. Our technicians will also install protective measures for gas meters to reduce the risk of gas leaks.
Reparing Foundations
During retrofitting, technicians may notice substantial foundation damage that needs immediate repair. Adding crawl space support posts and foundation piers, and stabilizing the walls are some of the ways TerraFirma can reinforce your foundation.

Homeowners Frequently Asked Questions
How does rain put my home at risk ?
SeaTac soils are impacted by heavy rains causing hydrostatic pressure. This leads to cracks in foundations and basements and may cause your foundation to settle or sink. Engineered support structures and comprehensive drainage systems are key to keeping your home dry, safe, and stable.
What’s the best way to repair concrete?
The NexusPro solution is a commercial grade joint sealant that offers several advantages over traditional concrete crack repairs. Its fast cure time (60 minutes) and performance under extreme temperatures makes it a perfect match for concrete repairs.
What types of cracks in my foundation or basement should I be concerned with?
Houses are susceptible to cracks in basements due to heavy rains and wet soils. Watch out for horizontal or stair step cracking along the foundation wall, diagonal cracks in the corners, crumbling walls and inward bulges.
How to fix a leaking basement floor?
If you have water coming through the floor or windows to your basement, the first step is installing a perimeter drain system. We can also install a direct drainage channel, which will help direct any water that comes through the crack into the drain and your sump pump.
Are you noticing damp drywall and carpet in your basement?
Musty smells, walls that feel damp to the touch, and ground-level leaks are all indicators that your basement may need to be waterproofed. Don’t wait until the next heavy rain to protect your home from water damage.
Which vapor barrier is best for weeping walls?
The VaporLoc Elite Wall System is better for weeping walls than other commonly used vapor barriers. The VLE system has double sealed seams, waterproof material (not water-resistant), and is much thicker than vapor barriers available at retail stores.
Can I turn my crawl space into storage?
TerraFirma offers comprehensive encapsulation solutions to keep your crawl space clean, dry, and secure from outside threats. Our industry-leading vapor barrier system keeps out destructive moisture while greatly improving your indoor air quality. In most homes, TerraFirma can even encapsulate your crawl space, giving you a clean, dry area suitable for storage.
How to repair damaged concrete?
While you could seal concrete with urethane caulk found at your local big-box DIY store, that is a solution that is prone to cracking, bubbling and drying out over time. The local experts at TerraFirma are here to help with long lasting solutions to level seal your unprotected joints and cracked concrete.
What is that bad smell coming up from my drain?
Unwanted air and gasses are coming up through your home’s drain system. A great fix is our TrenchLock™ drain insert that can be installed in an existing trench drain to allow water down without allowing air to come up. The system comes with balls that fit over the drainage holes, which create an airtight seal when there is no water.
What is the difference between helical piers and push piers?
Helical piers and push piers are both types of foundation repair methods, but they differ in their design and installation process. The choice between helical piers and push piers depends on factors such as soil conditions and structural requirements. Helical piers are often preferred in areas with weak or unstable soil conditions.
How long does basement waterproofing last?
TerraFirma-installed waterproofing systems are expected to last decades with regular care & maintenance. We also warranty our installations, our WaterGuard and DryTrak drainage systems come with a transferrable lifetime warranty. Terms apply, view the details here. We stand by our work and the quality of the systems we install.
